The LT7 makes enormous power from the factory, but it breathes through an airbox carried over from the Z06's LT6. Ask the twin turbos for more and that airbox becomes the restriction. The Eventuri Carbon Intake System for the C8 Corvette ZR1 Coupe replaces it with a larger, fully carbon fiber system designed around the ZR1 from the start.
The payoff shows up where you actually drive. On a stock C8 ZR1, Eventuri measured gains of up to 110 whp and 108 lb-ft in the mid-range around 5300 rpm, with peak gains of 36 whp and 101 lb-ft. The after runs were done at higher ambient temperatures than the baseline.
How the Eventuri C8 ZR1 Carbon Intake Makes Power
The factory trunk panel limits how big the intake can be. Eventuri redesigned that panel in clear polycarbonate, which freed up room for a high-volume intake and turbo inlet tubes with about 30% more internal volume than stock. More cross-sectional area means less pressure drop, so the turbos reach target boost more efficiently and earlier in the rev range.
At the center sits Eventuri's patented double Venturi filter housing. It merges two airflow paths into one high-volume chamber, then narrows gradually to speed up the air while keeping the flow laminar, the same principle as a velocity stack. Carbon fiber inlet ducts pull ambient air straight from the side vents and seal to the housing with a neoprene gasket, so engine bay heat stays out.
Coupe vs Hard-Top Convertible
This version comes with the clear trunk panel built for the Coupe, so the removable roof panel still stores in the trunk. If you drive a Hard-Top Convertible, order the HTC version instead. The two are not interchangeable.

Emissions and Legality
This intake does not have a CARB Executive Order. It is not legal for sale or use in California, or in states that follow CARB rules for aftermarket parts, on emissions controlled vehicles.
Installation Notes
Eventuri has not published an install time. This is a full intake system replacement, so we recommend an installer who knows the C8 ZR1. Some installed photos may show the alternate configuration.
- Work on a cold engine.
- Remove the factory airbox, inlet ducts, turbo inlet tubes and trunk panel as described in Eventuri's instructions.
- Install the Venturi housing, turbo tubes and inlet ducts, connecting them to the factory cold air feeds and turbo connections.
- Fit the clear trunk panel.
- Check every coupler, clamp and sensor connection, then start the engine and confirm there are no warning lights.
This is a final sale item. Confirm Coupe or Hard-Top Convertible before ordering. Eventuri's warranty and damage in transit support still apply.
